A year on and the rumour mill is back in full swing, with Premier League eyes drifting back towards Serie A.
Nainggolan has expressed a desire to remain at Roma in the recent past, but he has now hinted that a transfer could be in his thoughts while enjoying a well-deserved break.
While Chelsea and United continue to be linked with big-money bids for the Belgium international, both are also closing in on alternative midfield targets.
The Blues are looking to wrap up a deal for Monaco’s Tiemoue Bakayoko, with that deal likely to clear the path for United to complete a £40 million move for Nemanja Matic.
Nainggolan could still be on the move, though, with the 29-year-old one of European football’s most sought-after talents.
